So, for each subproject of a parent project, you want to record branch,
version (commit ID), and directory location. Not quite as easy to do in
a makefile but do-able.

I've been playing with this kind of subprojects a little bit.

My current approach is like this:

 * create a .gitmodules file which lists all the directories
   which contain a submodule.
 * the .git/refs/heads directory of the submodule gets stored in
   .gitmodule/<modulename> inside the parent project

Taking this a step further, you could make subproject/.git/refs/heads a
symbolic link to .git/refs/heads/subproject, with the benefit that fsck Just
Works.

Wouldn't an fsck in the parent complain about missing objects?

... not if my original idea (which I might have forgotten to mention ;-) 
was implemented: symlinking subproject/.git/objects to .git/objects.
